Screening Washer Compactor Booth No. 3545X-Tractor is designed to deliver superior screening washing and compacting performance. Screenings are transported to the unit via sprays or sluice troughs providing passive washing prior to the unit. Choppers, grinders, and macerators are eliminated. The X-Tractor is designed to handle higher water volumes and completes the washing and compacting process. Solids are discharged light in color, free of organics, and dry — easily passing a paint filter test. The washer soon will be available with a batch-washing process that shuttles solids in alternating directions, agitating the screenings to break up organics, with additional washing energy introduced through sprays controlled in a timed sequence. Headworks Inc. (Houston).Drying SystemBooth No. 4805This complete biosolids drying system is capable of handling up to 1000 ton of wet cake per day.
